----------------------------------------------------------
I see this issue with both Hibernate 3.6.8.Final and 4.0.0.CR6. We are using Spring 3.1.0.RC1. We use native hibernate, not JPA.
When adding the following relationship to our Lesson domainobject I see this issue.
{code}
@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(name = "RESOURCES_LESSON", joinColumns = @JoinColumn(name = "CODE_FS", referencedColumnName = "CODE_FS"), inverseJoinColumns = @JoinColumn(name = "RESOURCES_ID", referencedColumnName ="RESOURCES_ID"))
private Set<Resource> resources = new HashSet<Resource>();
{code}
We see this issue when fetching a Lesson (which is the domainobject which has the resources attribute shown above) in the following testcase:
{code}
@Test
public void resources() {
Lesson lesson = lessonDAO.findById("1234");
}
{code}
@Fabrice Daugan: Thanks for posting your comments! Since we see this issue in a "clean" fetching of an object I don't think we have any non persisted entities.
